Each of the ings i is also centrally aperi'nrecl to receive e. ohci-; pivot pin 9.

Walls are further The socket member 5, which is fulcruned in the main iraine or casing l, is provided with a pair oi sockets 5- and 5 disposed at :in angle to each otherpand both adapted to receive the removable handle member 14.

Un the upper ond of "the rack bar 2 is formed a tenon i5 (Fig. 4) that engages an undercut socket i6 inthe .lower sido ot' the head member formed lwith a pair oi? oblique opposltely disposed notches i7 adapted to seat a pan' ot links 180i a chain, the intermediate link 19 connecting the linlis 18 lying iiat upon the upper end of the head Liv, all in the manner clearly indicated in Fig'. Q. At the lower end of the chain formed by the links i8 and l!) is a grappie hook 20. The swiveled head 4 may easily be secured on thenpper end of the rack bar 2 ,withthe construction specitied by tomning through the upper end of said head one or more holes 21 3) through -Which a punch may conveniently be inserted to swage over the upper edge of the tenon 15 into the eountersink of the socket 16. The base 6 is preferably provided with the usual teeth 22 ony its under side to enable it to readily and strongly grip the surface on which it rests.

ln Figs. 7 and 8 I have illustrated a slight modification of the rigid tooth adjustment between the frame and the base. ln this 'form of the invention, the hase 6 is formed lwith parallel opstanding lugs 7',

(and the side Walls of the main frame or casing are provided with offset extensions or lugs 11 that overiap the lugs 7', and said lugs are connected, With capacity tor pivotaladjustment, by means of pivot pins 9 passingV through holes in the lugs 1l" and through slots 12 in the lugs 7. ln this form of the invention the lower edges of the laterally ofi'set frame lugs or 'extensions 11 are provided with ratchet teeth 23 that cooperatively engage a series oi' ratchet teeth 9.4- Jformed on the base 6 just outside the bases ot the lugs 7n Figs. 9, l0 and 11 illustrate a still iur ther modification of the same. structural principle. ln these figures G designates the base member formed with ya pair of 'parallel `upstanding lugs 7. Between said lugs is formed' a concave gear rack 25. Each of the lugs 72L is formed on its upper edge with a rounded, substantially semi-circular seat portion 26 and with a fiat horizontal stop shoulder y27. The lower end of the frame 'la is, in this case, solid, and is formed with a central semi-circular lug 28 that fits between the upstanding lugs 7:l of the hase and is formed. with a se1ni-circular rack 29 that engages and cooperates with the base rack in the manner clearly shown in Fig. il. The side lugs 7EL are apertured, and the central lug; 28 is slotted, as shown at 30 in' F50'.

The head member i is 11 to accommodate a through pivot.

materie pin 3l. The lower ends oi: the opposite v sides oi the irame 7a are formed with conca-ve shoulders 3&5 that rest upon the convex seats v26 and relieve the pivot bolt 3l of the strain. The lower ends ot the sides are also formed with straight shoulders 33. that, when the frame is in vertical position, engage the stop shoulders 27 of the base.

From the foregoing it wiil he readily seen that in all of the forms shown and described the teeth carried by the frame or casing,lr engage with and rest securely upon the teeth on the base member, thus securely holding: the jack casi-ng and its contained. parts rigidly with relation to the base; also that, in order to change the angular ositiou of the frame, as from the vertica p0- sition shown. in Fig# l to the inclined posi- .tion shown in Fig. 2, it is necessary only to grasp the frame, raise it to' the extent permitted by the slotted pivotal connection with the hase, tilt or lean it to the desired angle, and allow it `to return by gravity to a new position relatively to the stationary rack on the base.l l

id`ig--l2 illustrates a modified form of the swiveled head, wherein the head 4* is made oblong and is provided with central and end notches 34 'and 35, respectively, for engagenient with alternate links 18 of such a chain as is shown in Fig. 2, and, between the notches 34- and 35, with sockets 36 adapted to seat the intermediate links 19 of the chain. l

Both ofthe ,swiveled heads illustrated in Figs. l to Li inclusive and in ig. 12 engage the chain in a secure and anti-slip manner and without requiring any special fastening of the chain to the head.

Fig. 13 illustrates a very simple and c'onvenient form of handle bar 14 which is formed at one end with a diamond point 11F' adapted to enter the socket 5 or 5b of the posite end 14 serves the auxiliary purpose of a cliarnon(l poi1itbar. While the lifting tool of the'invention is preferably double 'or equipped with a handle member of the i form and functions last illustrated and described, in order to enhance the all-'around utility of the tool as a Whole, it will, of course, heunderstood that so far as the main structural features are concerned, they are not limited to that use in combination with 'this special form or handle.

From the foregoing description, taken in connection with the drawirigs, the utilit and advantages of my invention Will b readily apparent. lVhere the tool can he applied directly to or `beneath 'the article or object to' he raised, it is applied in the vertical form shown in Fig'. l, with the head or the vtoot of the jack directly engaged with `thc object to be raised, and .the handle `bar preferably in the vupper socket of the socket member 5. I Vnere a thrust is to be imparted in an inclined dlrection, the tool 'is adjusted tothe position typicallyillusrated in Fig. 2, for which adjustment it. is necessary only to lift the jack trame and its i-ontained parts, tilt it angularly relatively to vthe base, and let drop. If a lowlying,r object is to he raised that cannot be rt-ached liy the toot 3, the chain of the grapple can be applied to the swiveled head as shown in Fig. 2 with the grapple 20 at the proper height, and the Object elevated in this way; It the object is to one side ot' th'e jack, rather than directly in front of it, the swiveled head can be swung in either direction, thereby carrying the chain and grapple to either side of the Jack.v

The last described operations are equally capable of being perormedavith the apparatus when constructed in'cthe manner shown in Figs. 1v to 6 or in the manner shown in 7 and 8, or in the manner shown in i" Figs. 9 to 11. It will thus be seen that the tool of. the invention amounts, in effect, to a portable crane of what might be termed the lifting jack type. I am aware that it is old and known, broadly, to mount the frame of a lifting jack and its contained parts pivotally upon a base, with stops on'the. latter serving am aware, however, mylpresent invention isithcfirst to provide a tool wherein the frame of thczjack--can be adjusted to and rigidly held in any ofy a number of relatively Vinclined positions by mlere'ly raising the frame of-.the tool, tilting it to the desired angle, and allowing itto dropinto a position ofrest relatively'to the base. While 'believe the means for effecting the de- .jibed adjustability consisting essentially .the coperating teeth and the pin and slot `pivot. are the best means for effecting this result, yet, in the broader aspects of the in` rcntion, I do not limit the same to these structural features which are common to all ot' 'thtI forms of the invention shown. In naher respects, also, .it will be evident to those skilled .in the art vthat the described detailsof construction may be considerably modified without involvingr any departure from thc principle ot the invcntion'or sacrificing any of' the benefits and advantages secured thereby.
